Which C.S. Lewis book collects his 1940s broadcast talks on basic Christianity?

Mere Christianity collects C.S. Lewis’s 1940s broadcast talks on basic Christianity.

The talks were first broadcast by the BBC during the Second World War, beginning in 1941. Lewis aimed to explain shared Christian beliefs in accessible language rather than defend one denomination’s distinctive doctrines. The broadcasts were later revised and published in book form, with the title Mere Christianity.

The book is organized into sections commonly known as “Right and Wrong as a Clue to the Meaning of the Universe,” “What Christians Believe,” and “Christian Behaviour.” Lewis discusses morality, belief, pride, charity, and the Christian understanding of Jesus.

A frequent mix-up is treating Mere Christianity as a transcript of one uninterrupted lecture series. It grew from several sets of broadcasts and was edited into a book. It also differs from The Problem of Pain, which addresses suffering, and Miracles, which examines the possibility and meaning of miracles.
